EcoGraf Granted First Australian Patent for HFfree Purification
- EcoGraf granted Australian patent for its first original EcoGraf HFfree® purification technology
- Patent covers use of HFfree purification across battery anode, high purity graphite, and lithium-ion battery anode recycling
- Follows recent breakthrough in cost reduction, resulting in industry-leading low cost and high NPV for commercial scale Purification Facility
EcoGraf Limited has announced that IP Australia has granted the company an Australian patent for its first original EcoGraf HFfree® purification technology ('Patent Family 1'). The patent, numbered 2021261902, has a term of 20 years from the date of the patent (14 May 2021) and expires on 14 May 2041. This grant follows the May 2025 grant of an Australian patent for EcoGraf's second patent family, which provides broad protection of the company's HFfree purification technology flowsheet. The Australian patents cover the use of EcoGraf's HFfree® purification technology across a range of applications relating to the manufacture of battery anode material, high purity graphite products, and the recycling of lithium-ion battery anodes. This patent follows the recent announcement of a breakthrough process optimization that led to a 25% reduction in cost, resulting in an industry-leading low cost and stage 1 NPV of US$282m (A$433m) for EcoGraf's planned single-phase commercial scale Purification Facility. Protection of intellectual property rights is a key aspect of EcoGraf's vertically integrated battery anode materials business, which is underpinned by the use of low-cost and environmentally sustainable process technology. EcoGraf has also filed patent applications in other planned processing locations, including the EU, South Korea, Malaysia, and Vietnam, and has been granted patents for Patent Family 1 in the US, South Africa, and EAF (Tanzania, Mozambique, and Namibia).
EcoGraf's strategy is to locate its purification facilities in North America, Europe, and Asia-Pacific markets to support localized demand outside of China and to meet the increasing demand for battery anode material.
